Application led May 26, 1920. Serial No..f384,4`58.

To all whom t may concern: f Be it known that I, HALLrn Nonn1s,.a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and: State of Pennsylvania, have invented a newand useful Improvement in Spring-Oilers; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to devices for lubricating leaf-springs and for similar purposes, and it has for its object to provide a lubricating device of the character indicated which shall be simple and'ineXpensive in construction, and which may be easily and quickly appliedto the parts to be lubricated.

My improved spring oiler consists in general of a body of felt vorsimilar absorbent material of such a shape that it surrounds the spring or other part to be lubricated. For the purpose of retaining the felt in its proper shape and also for the purpose of applying spring compression to clamp the felt in position, I provide one or more strands of resilient wire such as piano wire extending through the body of the yfelt and giving it some degree of rigidity.

In the accompanying drawing Figure 1 is a side elevational view of an elliptical vehicle spring provided with several of my improved spring oilers. Fig. 2 is a perspectivev view of one of the spring oilers shown in Fig. 1. Fig. Sis a transverse sectional view of a vehicle spring having a modified form of my improved oiler attached thereto; Fig. 4 is a plan view of one of the spring oilers shown in Fig. 1. Fig. 5 is a plan view of a strip of felt reinforced with wire before it isshaped into the form shown in the other figures of the drawing; and Fig. 6 is a cross sectional view of a spring provided with a still further modification of my invention.

Fig. 1 of the drawing shows an elliptical vehicle spring 2 which may be of any ordinary or desired construction carrying, as shown, four spring oilers designated generally by the numeral 3. Each of these oilers is of the construction better shown in Figs. 2, 4 and 5, and consists of a strip 4 suitably of heavy felt fabric having one or more wires 5 extending centrally therethrough. The strip 4 may have a central reduced portion 6. as shown in Fig. 5, or it may be of the same width from end to end, as indicated in dotted lines at 7 Fig. 5.' Before being placed in position, the strip 4 is bent into the shape shown in Figs..2` and 4, having two opposed U-shaped clamping portions 8 and an intermediate coiled portion 9. f

The wire contained withinv the feltistrip preserves the shape of theU-shaped'portions 8 and also imparts acertain degree of resiliency to the coiled portion 9, so that when the oiler is applied to the spring .or other vpart to be lubricated, theclampingfportions 8 are caused to gripthe springend hold the oiler in'position. y The form'of my device which I have Just described 'is used by soaking the oiler in suitable lubricating oil and applying it p to the spring to be lubricated. yThe felt gradually gives up its oil during the movement of ythe vehicleand thus maintains a film of oil onV the top, sides and bottom of the spring. It is to be noted particularly that the under Vportions of the clamping members 8 extend beneath the leaves of the spring and thus effectually oil the under side of the spring. This is a result which -is not obtained by the spring oilers heretofore used, and is a feature of special advantage because the` undersides of the springs, especially yon the lower half of an elliptical vehicle spring, are particularly liable to accumulate rust and dirt.

Fig. 3 shows a modified form of device in which an oil cup 10 is secured to the coil portion 9 of the oiler' by means, for example, of suitable clamping gears 11 and a retaining bolt.l2. This oil cup may Vbe'of any usual construction and serves to supply the oiler with lubricating oil for a considerable period of time.

Fig. 6 shows a modified form of oiler in which the U-shaped clamping portions 8,V

instead of being integral, are formed separately and in which the wires 5 extending through the sections of felt are gether by means of loops 13 and are extended at 14 to form supports fora comjoined topression spring 15. This form of my device operatesl like a pair of tongs, it being evident that when the wires 14 are grasped and forced together, the clamping portions 8 of the oiler will be forced apart and may be placed upon the spring to be oiled; and

that, when the wires-14are released, the

will clamp the sections 8 tightly The felt may be cut away from the wires outside of the wires 14, or, if desired, the felt at the tops of the sections spring l5 1n place.

may be slit to expose the wires 14 and may then be placed together',V as shown at 1G, thus giving a somewhat increased oil-absorbing capacity.

It is to be understood that the details of my device, as herein shown and described, may be variously modiiied within the scope of my invention, and therefore that no limitations are to be imposed upon the invention unlessv indicated in the appended claims.

What I Claim is:

1. A spring oiler comprising body of oil-absorbing material, and reinforcing means Contained within the said oil-absorbing material'.

2. A spring oiler comprising a body of oil-absorbing material, and resilient wire reinforcing means contained within the oilabsorbing material, and serving to retain the shape of said material. 3. A spring oiler comprising two opposed U-shaped members of oil-ahsorbing material, wire reinforcing means contained within said members, and resilient means disposed between the said members and tending to move the said members together.

4. A spring oiler comprising two opposed U-shaped members lof oil-absorbing material and wire reinforcing means contained within said members, the said reinforcing means being utilized between the said members to apply resilient pressure thereto to force the said members together.

. 5. A spring oiler comprising a strip of oilabsorbing material and wire reinforcing meanscontained within the said strip, said strip and wire being bent to form two opposed U-shaped clamping members and a resilient coil member disposed between the said clamping members.

6. A spring oiler comprising two opposed U-shaped clamping members composed of oil-absorbing material, a wire extending longitudinally through each of the said members, the said wires being looped together between the said members and being extended to' form handles, and a spring interposed between the said `extended wires or handles.

In testimony whereof, I, the said HALLm Norms, have hereunto set my hand.
